The first problem I have is charging the main batteries as they are down to 30%. Looking at the main plug with in the engine bay of the van it has a 7 pin connector wile the standard 3 phase power supply I have has only a 5 pin connector.

The plug has 6 poles and a earth when the 3 phase plug has 3 poles + earth and neutral. I have had a look in to this and spoken to a few electricians. As this van is ex council, its looking like the council have had this plug fitted to the van for extra safety. The centre pin looks like it a pilot pin, which I have been told is for safety as it stops arcing if the plug is pulled when power is being transferred.

Looking inside the plug I can see that it has Phase 1,2 and 3 which are black. The 4th pin has a blue cable indicating that it would be neutral . The 5th pin is empty and the 6 centre pin is the pilot which isn't needed as long as you have a switched power supply. It also has a earth.

I have now took the male plug off the vans extension cable and replaced it with a 3 phase standard 5 pin plug. As I now know what the cables are I have connected Phase 1,2 and 3 to the correct pins on the 3 phase plug. I have also connected the earth and neutral and insulated the pilot cable.

I am going to plug it in tomorrow and see if it charges. I will let you know how I get on.

Plugged the van in to the 3 phase supply and everything seems ok with the plug. The front fan came on and the display on the dash showed (In charge). The problem is now its not pulling any current as the display shows 0A. Anyone have a ideas of what may be wrong. I am thinking that there may be a fault with 1 or more battery cells and the charger is refusing to charge.
